Web browser access usually uses the standard HTTP service port 80. For greater
security
, you can change it so the remote router interface uses a custom port by entering
that number in the field provided. Choose a number between 1024 and 65535, but do not
use the number of any common service port. The default is 8080, which is a common
alternate for HTTP.

To access your wireless modem router from
the Internet, type your wireless modem
router’s WAN IP address in your browser’s Address field, followed by a colon (:) and the
custom port number. For example, if your external address is 134.177.0.123 at port
number 8080, enter the following in your browser:
http://134.177.0.123:8080
Note: The http:// is required in the address.
Static Routes
Static routes provide additional routing information to your router. Under normal
circumstances, the router has adequate routing information after it has been configured for
Internet access, and you do not need to configure additional static routes. Only configure
static routes for unusual cases such when you have multiple routers or multiple IP subnets on
your network.
Static Route Example
As an example of when a static route is needed, consider the following case:
• Y
our primary Internet access is through a cable modem to an ISP.
• Y
ou have an ISDN router on your home network for connecting to the company where you
are employed. This router’s address on your LAN is 192.168.0.100.
• Y
our company’s network address is 134.177.0.0.
When you first configured your route
r, two implicit static routes were created. A default route
was created with your ISP as the wireless modem router, and a second static route was
created to your local network for all 192.168.0.x addresses. With this configuration, if you
attempt to access a device on the 134.177.0.0 network, your router forwards your request to
